Freescale vs Chipcon 802.15/Zigbee xcvr

Started by Andrew M March 15, 2005
Just wondering - has there been significant testing / comparison between 
Chipcon and Freescale 802.15 transceivers? Which has the better RF 
performance?
Any other features that stand out between the two?

They seem similar to the naked eye..

thanks

All I've found is http://blogger.xs4all.nl/ivonoorh/articles/4269.aspx The Chipcon & Ember 2420 parts should have the same data, as they are actually the same silicon.

The Freescale 2.4 GHz transmit/receive circuitry is more complex, so there is slightly greater scope for errors in the PCB design & product manufacture. Now that Chipcon has bought Figure8, will Freescale continue to license the Zigbee software from their competitor? Jeremy Bentham Iosoft Ltd.
From a support point of view, I'd worry about Freescale.  We were
initially interested in their products and found that they would not
return our (several) queries and calls.   Small companies & start-ups need
not apply, I guess.
